I can't comment on the nutritional value, but bacon grease will store damn near forever.
Also, try planting sunflowers. They won't stand out because most people will just think it's a giant yellow flower.
Great recommendation. People with peanut allergies can use the seeds, shelled obviously, to make their own sun butter. It's a very tasty substitute.
When we're thinking about fats keep in mind you want to get the right type. Bacon grease will store, but long term it's horrible for you. In fact, recent studies have linked pork consumption to MS.
Soy is a good source for polyunsaturated fats, but don't buy off the shelf soy beans, milk, or processed. ALL soy in the US is GMO unless you buy specified non GMO organic seeds and grow them yourself. Tofu, fish, safflower oil, and walnuts are other good sources for polyunsaturated. Personally though, nut wise, I'd go with Brazil Nuts. Google it real quick to see why.
Good monounsaturated fats will come from peanut butter, nuts, sesame oil, sunflower oil, and avocados.
As far as saturated fat, coconut oil. Buy organic extra virgin. Also is great for your teeth. Recent studies have been shown to fight cavities better than fluoride.
Hope that's somewhat useful.
